Problem this snippet solves:

If you want to add or delete a single VLAN from a route domain without sending in the entire list of VLANs, you can use this CLI script.

How to use this snippet:

Sample REST calls:

curl -sk -u admin:admin -H "Content-Type: application/json" -X POST https://your-ip-address/mgmt/tm/cli/script -d '{"command":"run","name":"modifyRouteDomainVlans","utilCmdArgs":"myroutedomainname vlan3942 add"}'

curl -sk -u admin:admin -H "Content-Type: application/json" -X POST https://your-ip-address/mgmt/tm/cli/script -d '{"command":"run","name":"modifyRouteDomainVlans","utilCmdArgs":"myroutedomainname vlan3942 delete"}'

Code :

cli script /Common/modifyRouteDomainVlans {  
proc script::run {} {  
 if { $tmsh::argc !=4 } {  
 exit 123  
 }  
 set zero [lindex $tmsh::argv 0]  
 set routeDomain [lindex $tmsh::argv 1]  
 set vlanName [lindex $tmsh::argv 2]  
 set command [lindex $tmsh::argv 3]  
 tmsh::modify /net route-domain [lindex $tmsh::argv 1] vlans [lindex $tmsh::argv 3] "{[lindex $tmsh::argv 2]}"  
 exit 0  
 }  
}

Tested this on version:

13.0
